Fire rated sealant for homes and businesses in Bentley Heath
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That’s the part we focus on, one gap at a time. We work on linear gaps, flats & HMOs and plasterboard & masonry, and people most often call us about cracked or shrunken fire-rated sealant and standard silicone or caulk in a fire-stopping gap.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Bentley Heath, and room-by-room programmes can be planned where needed.
All our work comes with a one-year guarantee.

Workplaces and buildings in Bentley Heath
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you let a flat or house near Potters Bar station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Bentley Heath is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- Clear items away from the joints we’re working on

Common problems we fix in Bentley Heath
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
Common reasons people contact us include:
- Door frames with gaps between frame and wall
- Ordinary sealant used where a fire-rated product was needed
- Gaps flagged on a fire risk assessment
- Fire stopping disturbed by later work
For buildings such as Church of King Charles and the Martyr, older buildings that have had new heating or wiring often have service gaps worth checking.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Store the list of sealed gaps with your building paperwork
- Check whether a sealant can be painted before decorating over it
- Allow for resealing whenever new services are run
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
Different surfaces, different methods
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment room by room.
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.

Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Landlord and commercial work in Bentley Heath
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
We work for landlords and agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
Bentley Heath questions
I let a flat near Potters Bar station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Can you do fire rated sealant in Bentley Heath?
Yes. Our work covers London and the South East, and Bentley Heath is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Can you tell me how many minutes the seal will last?
We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.
What does fire rated sealant cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
